Review on 🪚 XXGO 4-Piece Diamond Segment Swing Semi Circle Oscillating Multi-Tool Grit Grout Saw Blades - Model XG4002D by Joe Michels

I bought these blades for a little homework to remove rotting mortar. I used a tomahawk shaped blade because the ends can remove the grout down to the undamaged area. I stripped the grout from the 7-4 inch long edges and found in the end that the "diamond" edge on the rounded portion of the blade was badly degraded and smooth in places. Not to say that it would be better by hand, no, I can say that with a big job you have to change blades on the fly; Maybe there is a better blade that will last longer. Also, this blade is too thick to use if you want to keep the edges under 1/8 inch.
